Python 在Rocket.Chat API中循环

Python 3.7.2 皮查姆

我对Python和API交互相当陌生；我正在尝试循环使用Rocket Chat的API，特别是将用户的电子邮件地址拉出。 与我能找到的几乎所有例子不同，Rocket Chat没有使用任何类似“Next”的构造—它使用计数和偏移量，而我实际上使用了计数和偏移量 不过这可能会更容易。 我已经设法让第一部分开始工作了， 在JSON上循环并获取电子邮件。我需要做的是循环通过API端点，这就是我遇到的一些问题。
我已经看过这个答案了 因为它似乎非常接近我想要的，但我无法让它正常工作

下面的代码是我现在拥有的；显然，这还没有通过API端点进行任何循环，只是在返回的json上进行循环

import os
import csv
import requests
import json

url = "https://rocketchat.internal.net"
login = "/api/v1/login"
rocketchatusers = "/api/v1/users.list"
#offset = "?count=500&offset=0"


class API:

    def userlist(self, userid, token):
        headers = {'X-Auth-Token': token, 'X-User-Id': userid}
        rocketusers = requests.get(url + rocketchatusers, headers=headers, verify=False)
        print('Status Code:' + str(rocketusers.status_code))
        print('Content Type:' + rocketusers.headers['content-type'])
        userlist = json.loads(rocketusers.text)
        x = 0
        y = 0
        emails = open('emails', 'w')
        while y == 0:
            try:
                for i in userlist:
                    print(userlist['users'][x]['emails'][0]['address'], file=emails)
                    # print(userlist['users'][x]['emails'][0]['address'])
                    x += 1
            except KeyError:
                print("This user has no email address", file=emails)
                x += 1
            except IndexError:
                print("End of List")
                emails.close()
                y += 1

我所尝试的和我想做的，都是一个简单的FOR循环。实际上，可能有很多方法可以实现我的目标，我只是不知道

大概是这样的：

import os
import csv
import requests
import json

url = "https://rocketchat.internal.net"
login = "/api/v1/login"
rocketchatusers = "/api/v1/users.list"
offset = "?count=500&offset="+p
p = 0

class API:

    def userlist(self, userid, token):
        headers = {'X-Auth-Token': token, 'X-User-Id': userid}
        rocketusers = requests.get(url + rocketchatusers+offset, headers=headers, verify=False)

        for r in rocketusers:
            print('Status Code:' + str(rocketusers.status_code))
            print('Content Type:' + rocketusers.headers['content-type'])
            userlist = json.loads(rocketusers.text)
            x = 0
            y = 0
            emails = open('emails', 'w')
            while y == 0:
                try:
                    for i in userlist:
                        print(userlist['users'][x]['emails'][0]['address'], file=emails)
                        # print(userlist['users'][x]['emails'][0]['address'])
                        x += 1
                except KeyError:
                    print("This user has no email address", file=emails)
                    x += 1
                except IndexError:
                    print("End of List")
                    emails.close()
                    y += 1
        p += 500

https://rocketchat.internal.net/api/v1/users.list?count=500&offset=0
https://rocketchat.internal.net/api/v1/users.list?count=500&offset=500
https://rocketchat.internal.net/api/v1/users.list?count=500&offset=1000
https://rocketchat.internal.net/api/v1/users.list?count=500&offset=1500

现在，很明显这不起作用，或者我不会发布，但是为什么它不起作用是个问题。 get report的错误是，当需要STR时，我无法连接INT。好的。当我尝试类似于：

str（p=0） 我得到一个类型错误。我也尝试过很多其他的东西，其中很多都很愚蠢，比如p=[]，p={}和其他更激进的想法

URL（如果不是所有变量和连接的话）将如下所示：

import os
import csv
import requests
import json

url = "https://rocketchat.internal.net"
login = "/api/v1/login"
rocketchatusers = "/api/v1/users.list"
offset = "?count=500&offset="+p
p = 0

class API:

    def userlist(self, userid, token):
        headers = {'X-Auth-Token': token, 'X-User-Id': userid}
        rocketusers = requests.get(url + rocketchatusers+offset, headers=headers, verify=False)

        for r in rocketusers:
            print('Status Code:' + str(rocketusers.status_code))
            print('Content Type:' + rocketusers.headers['content-type'])
            userlist = json.loads(rocketusers.text)
            x = 0
            y = 0
            emails = open('emails', 'w')
            while y == 0:
                try:
                    for i in userlist:
                        print(userlist['users'][x]['emails'][0]['address'], file=emails)
                        # print(userlist['users'][x]['emails'][0]['address'])
                        x += 1
                except KeyError:
                    print("This user has no email address", file=emails)
                    x += 1
                except IndexError:
                    print("End of List")
                    emails.close()
                    y += 1
        p += 500

我觉得我错过了一些非常简单的东西。我有理由相信答案在我列出的帖子的回复中，但我无法让它发挥作用。

所以，在四处询问后，我发现我一直在正确的道路上解决这个问题，我只是在错误的地方尝试了。以下是我最终得到的结果：

    p = 0
    while p <= 7500:

            rocketusers = requests.get(url + rocketchatusers + offset + str(p), headers=headers, verify=False)
            print('Status Code:' + str(rocketusers.status_code))
            print('Content Type:' + rocketusers.headers['content-type'])
            print('Creating the file "emails" to use to compare against list of regulated users.')
            print(url + rocketchatusers + offset + str(p))
